Application filed september To all whom imag Concern.:`

Be it known that ALBERT H. REIBEB, a citizen` of the United States, andresident of the Bronx,in thecoimty of Bronx and State of New York, hasinvented certain Improvements in Selectors,of which the following is aspecication.N s* t Printing telegraph systems. ofmodern type include atransmitting station and re,- ceiving stations which4 latter may jbekconnected over a number of vindividual lines tO a plurality ofsubsidiary stations.y VThe present invention providesmeansforautomatically selecting any ofthe individual lines to whichconnection is desired. Y

The drawing illustrates a diagram of a re'- ceiving .station to whichreight individual` lines .are connected. A transmittingk sta- -tion isschematically indicated.k -Both sta-v tions -fmay be combinedy in oneunit. 4The selection of individual Alines is loriginatedy by means ofcodefsignalsaccording to the Baudot or similar codes, translatedby meansof a perforated "tape, which signals r,may preferably comprise a'blanksignal and inf 1 clude such other signals as normally, are used,

for effecting various mechanical.v functions of a telegraph-printer. u fY v Printing telegraph ,apparatus to, which the` present invention ispeculiarly adapted is disclosed in applications for U.

though it is understoodthat any other transf mitter, includingl aykeyboard-transmitter, may beused. The movable tongue of transmitter 10may be'connected over vline 11 to 'the receiving unit of the apparatus,if desired,^located at a distant station. A con ductor 12, leads fromline y11 through va resistance 13 to a polarized line-relay 14, having amovable contact-tongue 15,-,playing between marking contact 16 andspacing contact 17. A conductor 18 connects mark- ,ing contact 16 l.withupper winding 19 of control relay 20, a conductor 21 further con-`nectswinding 19 with start magnet 22, from where conductor 23 '-24 ofdistributor-head 25. brush-arm26 travels overV the face of thevdistributor-head,in the direction of Athearrow, indicated in. thedrawing, and connects the outer ring containing start seg- -ment 24andfsegmentsl, 2, 3, 4, k5 and '6,

with battery-ring ductor28 leadsto positive pole of battery 29,tlienegative pole of Which is connected byv k*means `of. conductor 15 .ofline-relay 14. Y.

The energization of control relay 20 results in the attraction ofarmature 31, connected by means of conductor 32 to sixthimpulse-segment33 of distributor-head 25.

Traveling arm 26 of distributor-head 25 is' adapted to beengaged bydetentA 34, formarm 26 issecured on a frictio-irdrivenshaft,

leads to start segment A rotatableV 27, "and by means of conl`v` 3()y tocontact-tongue i v opens spacing contact-points 17 and again closesmarking contact-points' 16.-

Control relay 20 is provided with a second armaturer 35, which may beintegral with armature 31, and the fixed contactpoint for same isconnected, by means of conductor 36, to spacing contact-point 17, ofcontact-tongue ,15. The pivot of armature 35 is connected to oneterminal of Winding 37 of control relay 20, the second terminal of whichlleads to positive pole of battery 29. It will now be noticed'thatenerization of winding 37 of control relay 20, inthe event thatcontact-tonguef15 is" in vcontact withl spacing contact-'point 17results in the closing of a locking circuit for control relay 20, untilcontact-tongue 15, on proper venergization of polarized relay 14,

The energization y'of control relay20 and the attractionof armature 31,afterroper rotation of brush-arm 26, 'results in t eV energization ofreleasing magnet 38, over conductor 39, leadingr to one terminal of itswinding, the second terminal of which leads to negative pole of rbatteryr29, over conductor 40. Releasing'magnet 38 is provided witharmature-lever 41,having a detent 42 adapted to engage one ofthe teethvof ratchet 43 and forming the holding pawl for the ratchet against thetension of spiral-spring 44;.- Armature-lever 41 acts upon one arm ofbiased latch y45, the'second arm'of which normall supports the end'ofarmature 46,-

i Operation. f

The drawing shows a'schematic wiring diagramrof a transmitting stationfor send@ ing signalsv to any one :of a number of departments orsub-stations over lines to VIII, inclusive. Y l Y In' order toautomatically select,n preferably by means of a perforated tapeanyone-of the different sub-station lines, ythe procedure 58 forces the`end of stepping pawl 56 agalnst the teeth of is, as follows z-Assumngthat a message is to be sentfto a sub-station over wire III, the blankcode-signal is first perforated on the tape, then three carriae-return-signals and then a. line-feed-signa 'The Vfunction of ytheblankcode-sivnal is to return the lever 59 to its point of rest againststop 61 and to set the mechanism so that the following 'lows2relay-tongue 15 then returns to, its

spaclng-contact-point 17, yand locks up relay 20, through armature' 35and winding 37. The contacts of armature 31 remainclosed while brush-arm26 passes over segments 1,

2, 3, 4 and 5, and moves to sixth-impulse- Asegment 33.l When brush 26reaches sixthimpulse-segment 33, magnet 38 is operated and permitsspring 44 to return arm 59 to stop 61. The energization of magnet 38also closes contact-springs 49 and 50, thereby providin afpath from thefourth-segment 51 of distri utor-head 25 to stepping magnet 54. For eachcarriage-return-sl nal -thatfollows, therefore, arm 59 of'auxiliarydistributor-head 60 is ste ped forward by magnet 54 the distance o onesegment. If'the third lsub-station is desired, 'threecarriagereturn-signals areused to step arm 59 tothe third of thesegments 62, thereby connecting transmitter 10 and` line 11 directly toline III. `When now kthe next'-line-feed-signal is' received, magnet 47is operated, contactsprings 49 'and 50 are again opened' andloosubsequent carriage-return-signals cannot affect magnet54.

Magnet 38 is only operated when a .blankcode signal is sent. If, afterthe start irn- 'pulse is s ent, anyone or more lof the five selectingimpulsesare of marking vpolarity,A

line-relay-tongue 15 moves away from 'its spacing contact-point 17 andbreaks the locking circuit to'relay 20. While brusharm 26'0fdistributor-head 25 reaches in* its one yrevolution thelsixth-impulse-segment 33, therefore, the contact ofy armature 31l isbroken and themagnet 38l will not be operated so as to set the entiremechanism to normal. p l l The substance of the present invention,
